SMS Schlesien is one of five Pre-Dreadnoughts of the Deutschland class, not to be confused with the later class of Cruisers. Initially she was built for the Imperial German Navy, seeing service till the near end of the Second World War.


During the late 1800s, the German navy was changing and rapidly expanding, with funding for new vessels coming in through Flotten Gesetze or in English Naval/Fleet Laws, with the goal of competing with the Royal Navy.

The Second Naval Law allocated funding and a goal to build 38 Battleships by 1920, which started out with the Braunschweig class of battleships, setting the framework for the Deutschland class. The class differs in some ways such as replacing wing turrets with casemate mounted guns.

Plans were drawn up in 1903, and an initial design was started, Deutschland, which had some differences from the ships to come after her, notably in the boilers. Deutschland has a mix of fire-tube and water-tube boilers, while the ships that came after her had just water-tube boilers which overall are lighter. Weight savings from the change in boilers allowed the rest of the class to have slightly thicker armor belts. Schlesien herself was completed and commissioned into service in 1906-08, only a few months before HMS Dreadnought would come into service, rendering all Pre-Dreadnoughts obsolete.

Service History + Post War History

In the era before World War I, her service was calm and quiet, with very few events happening to her. Such as finally getting her full crew, doing some sailing around Europe, and being sent to the Second Battle fleet in 1911.

Once war was declared in 1914, she was deployed to defend the German Blight, seeing relatively minor service. Shortly after, Schlesien was transferred to help the Battlecruisers in their raid of Scarborough, but a decent number of vessels including Schlesien had to turn back with a major part of the fleet due to a Royal Navy threat. In 1916 Schlesien and her sisters joined the High Seas Fleet with the Dreadnought battleships to help the Battlecruisers. The Royal Navy intercepted, and a battle started, Jutland. Being second to last in the line, and followed by her sister ship Schleswig-Holstein, they did not see much action. In the evening, the Pre-Dreadnoughts went in to aid the Battlecruisers, taking some fire, but overall surviving. During the night, Royal Navy Destroyers attacked the Pre-Dreadnoughts, with Pommern, the lead ship in the line, being hit by a torpedo and having her ammo stowage detonated. Pommern went down with all hands lost. In total during the battle, Schlesien only lost one life onboard. After the battle, she was sent back to Germany, serving minor roles, mainly as a training vessel for the rest of the war.

Under the terms of the Treaty of Versailles, Germany was allowed to keep 8 older Pre-Dreadnoughts, Schlesien being one of them. Eventually two of the other Pre-Dreadnoughts became worn out and needed replacing, so Schlesien and her sister Schleswig-Holstein were brought out of mothballs. During the interwar period she received multiple refits, such as updating her boilers to be based, and removing the foremost funnel. Afterwards she would sail around the world and serve as a training ship.

When World War II broke out, she still served primarily as a training vessel, while occasionally being used as shore bombardment. Slowly her role and importance decreased, serving as an ice breaker, then as an escort with a skeleton crew, and eventually sailing back for her final refit and then usage again as a training vessel.

On May 3rd 1945, she was located by soviet forces after hitting a British mine, she was severely damaged causing most of the ships crew to be evacuated, while the AA gunners remained. On the 4th, Soviet aircraft attacked the small formation of ships that she was in, where at minimum a FAB-500 hit her. It is likely that also 2x FAB-1000s hit her, and possibly that a FAB-250 hit as well. Torpedoes were launched, but most likely due to multiple factors did not hit the ship. According to this account, at least one aircraft was downed, and 5 were damaged from this sortie. Due to the damage inflicted upon Schlesien, she was sunk.

Post War:

Some minor scrapping happened on the vessel from 1946-1956 but was mostly left intact. Scrapping started again in the 1970s.

Pardon some of the grammatical errors. There also has been more research done since the creation of the suggestion. Research is still actively going on for personal interest.

I really hope we get some of the later pre-dreadnaughts and semi-dreadnaughts, especially the German ones that even served in WW2. Schlesien’s sister Schleswig-Holstein would make sense in WT and could be a great premium considering her history


Schleswig-Holestiens history is interesting as well, due to a few things. She never got a complete set of oil burning boilers, i forgot the exact number, and will get that number later from the relevant Warship 2014 article. Then also being relfoated post war and sunk again as a target ship. Some of her wreck is still around, with this 3d scan showing it here and a video to help show things better here. Most people associate her with being the ship to fire the first shots of the war.

Shleswig-Holstien in a second phase of refitting during may/july had her after two boiler rooms converted to oil firing to match her sister… Schlesien had again been refitted, her forward (coal-fired) boilers being removed, and the space being adapted for additional cadet accommodation This resulted in the removal of the trunking from the forward funnel, adding a further means of distinguishing between the two sisters

1935 is when the intitial refit on S-H happened in the context of the quote. In Schlesiens case this refit was done in 38/39, before her South America Voyage. Albiet, I need to find more information on Schlesien’s refit here, as some imagery seems conflicting about this refit and change in appearance. There is a nice diagram from within the book that does show hypothetically what they are supposed to look like

At the end of 1943 with the sinking of Scharnhorst, Schleswig-Holestiens reactivation was once again contemplated. In her favour besides her big guns was that she retained some coal-fired boilers, given the ever worsening oil supply situation that was heavily circumscribing Schlesiens ability to provide seagoing training - she having lost her coal firing ability in 1939 when her forward boilers had been stripped out.

The qoute goes on about how both got reactivated again as training ships, then made as convoy escorts. Thus requiring them to go to port for some modernization, mostly of their AA Batteries. Interestingly the FuMB-6 was not mounted on S-H.

All information in this comment comes from “Last of the line, The German battleships of the Braunschweig and Deutchland classes” by Aidan Dodson in Warship 2014. For the purposes of the suggestion I was not able to get this article in time.

If you want some more specific Information, feel free to ask.


Doing some more research, netted some good information about the ship, most notably confirming the lack of forward trunking, and there not seeming to be much in terms of camo on the ships hull. Found an image of her wreck. The caption of the photo also mentions:

“The flag is still lowered after the announcement of the ‘Fuhurs’ Death. a few days earlier” (Nottlelman, pg 88).

That lines up due to Hitler dying on 30 April 1945, and the ship being abandoned 3-4 May 1945. The source also confirms in English the Red Army’s attack on the vessel. Funnily enough the source mentions during scrapping and removal of one of her forward guns, a shot was fired, injuring no one.

I have no idea why im continuing to update this thread.
